No, it expands the note area. The left bar used to be twice as wide. The bottom bar is just a sliver.

L isn't used. I'm not sure what it was intended for @bu5hm4nn ? @daniele ? R is for relay connection confirmation, authentication confirmation, NIP-46 request confirmation. P is for pending items (usually lists out of sync or haven't been published recently). Also the bottom bar gets the message area and the go-offline switch so it's not wasted.

L was intended to capture general app Logs, but we need to decide how to segment them and surface the most important (critical) ones, so the user is alerted with the counter and the change of color.
